We have developed an easy-to-use online tutorial generator designed to allow instructors to make tutorials quickly and with a minimal learning curve. The motivation was to create a generator that would allow instructors to create tutorials as needed

A simplex algorithm used to solve molecular structure from asymptotic momentum values is reported. The geometry of CO 2 3 + molecular ions in linear and bent configurations is reconstructed. A polyatomic molecular ion with trigonal planar symmetry is

Momentum vectors of fragment ions produced by the Coulomb explosion of CO2z+ (z = 3–6) in an intense laser field (~50 fs, 1 × 1015 W cm−2) are determined by the triple coincidence imaging technique. The molecular structure from symmetric and asy

We have used a wavefunction-modified Ammosov–Delone–Krainov (ADK) method to calculate the ionization rates of H2, N2 and CO2 as a function of initial vibrational level of the molecules. A strong increase in the ionization rate, with vibrational l

The Cooper minimum (CM) has been studied using high harmonic generation solely in atoms. Here, we present detailed experimental and theoretical studies on the CM in molecules probed by high harmonic generation using a range of near-infrared light pul

We demonstrate that high-order-harmonic generation (HHG) spectroscopy can be used to probe stereoisomers of randomly oriented 1,2-dichloroethylene (C${}_{2}$H${}_{2}$Cl${}_{2}$) and 2-butene (C${}_{4}$H${}_{8}$). The high-harmonic spectra of these is

High harmonic generation in unaligned molecular isomers is shown to be distinguishable and is attributed to differences in angle dependent sub-cycle ionization yields.

We report detailed measurements of high-order harmonic generation in a series of complex, unaligned, polyatomic molecules and show that fingerprints of electronic structure are embedded in harmonic spectra.

We used Coulomb explosion imaging (CEI) to observe enhanced ionization (EI) in nitrogen and carbon dioxide molecules. In N 2 we observed electron localization with time-resolved CEI using few-cycle laser pulses. In CO 2 we reconstructed molecular str
